Analog Computer Solution Of The Unsteady Flow Equations And Its Use In Modeling The Surface Runoff Process, Utah Water Research Laboratory

Reports

The flow of water on a watershed is usually unsteady and spatially varied, but can be adequately portrayed by the equations of momentum and continuity, commonly referred to as the unsteady flow equations. Because these equations are quasi-linear, hyperbolic, partial differential equations, they are not easily amenable to solution. Analog computer model~ of surface runoff generally have been based on simplified forms of these equations. As an improvement of those models, an analog computer solution is presented here for the unsteady flow equations. The solution involves the conversion of the partial differential equations in to a differential-difference system, and a …

Snowmelt Simulation, J. Paul Riley, Duane G. Chadwick, Keith O. Eggleston

Reports

The rapid growth in recent years of a variety of demands upon available water resources has lead to an increasing interest in more fundamental approaches to the science of hydrology. Accompanying this growth has been a need for an increased understanding of the snowmelt process. A completely adequate description of the entire physical process of snowmelt under all conditions is not yet available. The complex interrelated and variable nature of the snowmelt processes that occur simultaneously complicate the problem. A preliminary mathematical model of the snowmelt process has been developed in which processes such as pack settlement rates and energy …

Influence Of Mountain Groundwater On Streamflow, Bi-Huei Wang, Roland W. Jeppson

Reports

This investigation has determined the quantities of water stored as groundwater in the three watersheds in Utah, Logan River upstream from State Dam, South Fork Ogden River upstream from Huntsville, and Weber River upstream from Oakley. The proportion of the total streamflow contributed from this groundwater storage has been determined from past streamflow records, and the knowledge obtained from the analysis of groundwater contribution to streamflow has been utilized in developing water supply forecasting techniques and procedures. The first phase of the study dealt with theory and methods from separating the groundwater component from the total streamflow hydrograph. The method …

Usu Telemetering Precipitation Gage Network, C. Earl Israelsen, Don L. Griffin

Reports

A network of telemetering precipitation gages is operating in the mountainous areas of northern Utah, western Wyoming, and southern Idaho as part of the Wasatch Weather Modification Project. Approximately 40 individual gages collected and reported data during the 1968-69 winter season from distances up to 130 miles. In addition to the remotely located gages, the system includes an Automatic Readout Console (ARC) at the Utah Water Research Laboratory that is connected by a cable to a translator on top of Mt. Logan. The ARC is the control center for the network, interrogating in a predetermined programmed sequence the remote telemetry …

Cutthroat Flow Measuring Flumes For Flat Gradient Channels, Gaylord V. V. Skogerboe

Reports

The cutthroat flume can operate either as a free or submerged flow structure. Submerged flow calibration curves and free flow equations have been developed. Rectangular cutthroat flume sizes of 1, 2, 3, 4, and 6 feet were studied and tested in the laboratory. Trapezoidal cutthroat flumes having zero (or V-shaped), 6-inch, and 12-inch throat widths were calibrated. The value of transition submergence is listed for each of the rectangular and trapezoidal cutthroat flumes. The most obvious advantage of a cutthroat flume is economy, since fabrication is facilitated by a flat bottom and removal of the throat section. Another advantage is …

Electronic Analog Computer Simulation Of The Paez-Pedraza Region Of Venezuela, J. Paul Riley, V. V. Dhruva Narayana, Kousoum S. Sakhan

Reports

Recently governments and universities in many South American countries have shown considerable interest in a planned and orderly development of available water resources. A case in point is the preliminary study reported in which the problem is approached by utilizing a general mathematical model of the hydrologic system. Specifically, the study involves simulation by means of an electronic analog computer of the hydrology of the Paez-Pedraza region of south western Venezuela. The various processes within the model are linked by the continuity-of-mass principle, which requires a hydrologic balance at all points. The analog computer is ideally suited to the solution …

A Theoretical Study On The Interpretation Of Resistivity Sounding Data Measured By The Wenner Electrode System, Siew Hung Chan

Doctoral Dissertations

"This thesis deals with a theoretical study on the interpretation of resistivity sounding data measured by the Wenner electrode system. The objectives of this investigation are twofold: (i) to derive from the apparent resistivity data some suitable functions from which the resistivity and thickness of each member of the sequence of layers composing the earth may be determined, and (ii) to devise suitable methods for analyzing the resulting functions. In this investigation it is shown that the solution of the boundary value problem associated with an n-layered earth model leads to an integral equation for the Wenner electrode system. This …

A Theoretical Model For Gas Separation In A Glow Discharge: Cataphoresis, Fredrick H. Shair, Donald S. Remer

All HMC Faculty Publications and Research

A theoretical model for transient and steady-state cataphoresis is developed starting with the macroscopic equations of continuity. After a brief breakdown period, the impurity ions are assumed to be closely coupled with their neutral counterparts. The basic assumptions in the model are that after breakdown, the level of ionization of the impurity, and the axial electric field remain constant; it is demonstrated that under these conditions a system involving rapid ionization-recombination reactions is equivalent to a system in which no reaction occurs, but in which the "effective'' ion mobility is a product of the true ion mobility and the fraction …
